The instructions that come with them are quite detailed. You may be able
to call them and get a set. I've found them quite helpful on the phone for
aany of their products.

The one thing you have to watch with the Sandpoint is that it shuts off
the solenoid when the pH drops .02 below the preset point. Excess CO2
in the reator at that point will continue to drive the pH down. (Yes, it
can even be a problem in my 225 gal) I set the bubble rate so the the
CO2 just barely holds on to the pH. It only comes on a couple hours
after the lights and only shuts off a couple times a day. (briefly)

It is neophrene. You can by it and other CO2 safe tubing from your local
welding supply.
